342 THE CANADIAN ENTOMOLOGIST. 



Stripe was traceable but faint along the whole of dorsum, and tubercle iv 

 had nearly all the bristles rust-red. In this larva the spiracles on the three 

 posterior segments were black. 



A third specimen was the same as the description above. 



A fourth specimen had tubercle i on first three abdominal segments 

 tipped with pale yellow, and nearly all the bristles on the dorsum of the 

 thoracic segments were dark dull, rusty red ; tubercle ii on anterior 

 abdominal segments was touched with yellow as in the seco'nd specimen 

 above noted, and tubercle iv had bristles all rust-red. 



A fifth specimen showed no differences from any of the above. 



A sixth specimen had a faint dorsal stripe on all segments, but other- 

 wise had no characters other than those noted above. 



In all the specimens tubercle iii was yellowish, and iv, v, vi, vii and 

 viii reddish. In some tubercles i and ii are wholly black, in others these 

 are tipped with yellow. In all the larvae the thoracic feet and prolegs 

 were reddish. The dorsal stripe was faintly present on all the segments 

 in some specimens, while in others it was only noticeable on the thoracic 

 segments. 



Towards the end of May, 1903, Mr. C. H. Young also gave the 

 writer three mature larvae of parthenice, which were found by him at 

 Meach Lake, a short distance from Ottawa, Notes on these were taken 

 on May 28, on which date they were 42 mm. in length. 



Specimen No. i had a flesh-coloured dorsal stripe indistinct in the 

 incisures. Tubercles yellowish, those below the spiracles with a reddish 

 tinge. All the feet distinctly reddish, about the same colour as the 

 rust-red bristles from lower lateral tubercles. Began to spin cocoon June 

 6, emerged ? moth July 6. 



Specimen No. 2 same as No. i, only tubercles i and ii black, summits 

 of others yellow, bases black, excepting ventral tubercles, which are 

 wholly blackish. Feet all reddish. 



Specimen No. 3 : Tubercles i and ii wholly black, summit of iii 

 yellowish, iv and v nearly all yellowish, ventral tubercles yellowish-red. 

 All the feet reddish. Moth emerged July 16. 



Another larva found April 20, 1904, by Mr. W. Metcalfe, and handed 

 to me, moulted on May r, on May 23, and again on June 2. On June 24 

 this specimen measured 41 mm. in length, but then suddenly died. It 

 had a faint dorsal stripe, tubercles i and ii black, iii pale yellow, others 

 reddish-yellow. All the feet reddish. I have little doubt that this larva 

 was also that oi parthenice.
